The new feature means that the system password now only needs to be entered once per session:

If you have ever needed to build a new security model for Dynamics GP, you will have become heartily sick of having to enter the system password multiple times. In fact, every single time a protected window was opened, the password needed to be entered.

This feature is a most welcome one, but has one drawback. Once entered, the system password is remembered for the rest of the session. This means if you enter it for a user, such as, for example, to give them access to the VAT Return window, they can then access any other window which is usually protected with the system password.

This shouldn’t generally be a problem as the security roles would have locked down the security windows so normal users wouldn’t see them, but it is something to be aware of and consider.
